The housefly (Musca domestica) is a fly of the suborder Cyclorrhapha.It possibly originated in the Middle East, and spread around the world as a commensal of humans.Adults are gray to black, with four dark, longitudinal lines on the thorax, slightly hairy bodies, and a single pair of membranous wings.
Even though the ostrich is a bird, it can’t fly. Ostriches have wings, of course, but they are too small to support their weight. In addition, birds need keel-shaped sternums for flight, and ...
Birds (flying, soaring) – Most of the approximately 10,000 living species can fly (flightless birds are the exception). Bird flight is one of the most studied forms of aerial locomotion in animals. See List of soaring birds for birds that can soar as well as fly. Townsends's big-eared bat, (Corynorhinus townsendii) displaying the "hand wing"
Myiasis (/ m aɪ. ˈ aɪ. ə. s ə s / my-EYE-ə-səss [1]), also known as flystrike or fly strike, is the parasitic infestation of the body of a live animal by fly larvae that grow inside the host while feeding on its tissue.
Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly.They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments.
When such a cultured disc is eventually implanted in the body of a larva that is allowed to pupate, the disc will develop into the structure it was originally determined to become. That is, an antenna disc can be cultured this way and will, almost always, become an antenna (out of place, of course) when final development is triggered by ...
Birds use wing-assisted inclined running from the day they hatch to increase locomotion. This can also be said for birds or feathered theropods whose wing muscles cannot generate enough force to fly, and shows how this behavior could have evolved to help these theropods then eventually led to flight. [18]
Some species lacking wings are members of insect orders that generally do have wings. Some do not grow wings at all, having "lost" the possibility in the remote past. Some have reduced wings that are not useful for flying. Some develop wings but shed them after they are no longer useful.
